Abstract

L'invention concerne un moteur à deux temps de configuration particulière qui peut voir sa puissance de sortie augmentée en faisant marcher de plus gros pistons et en utilisant des orifices dans la jupe de piston à travers lesquels de l'air comprimé, arrivé à l'intérieur de la jupe par de courts passages dans le logement de cylindre, est conduit de l'intérieur de la jupe au volume au d'ouverture dessus du piston. Grâce à cela on peut utiliser un plus grand piston avec le même espace et la même dimension d'ouverture dans le bloc, ce qui évite d'avoir à redessiner le bloc et le vilebrequin. Un réglage de position pour le piston le déplace axialement sans qu'il y ait rotation des orifices de piston, ce qui les désalignerait des orifices d'admission dans le logement. On maintient la tige de piston dans la crosse de piston à l'aide d'un plat tandis qu'un écrou de réglage crée en tournant un mouvement axial de la tige de piston, un écrou de blocage assurant la position finale du piston.
